To all whom it may concern:

I 3e it known that I, HEN YIC. HUNTER, cltizen ofthe United States,residing at Jersey Clty, Hudson county, New Jersey, haveinvented'certain new and useful Improvements in Compounding-Machines forManufacturing Paper or Pasteboard, of which the following is aspecification;

My invention relates to a compounding machine by which a compositearticle is produced in the form of a' fiber board having an adhesivesubstance incorporatedwith the fibrous structure of the board and alabel p sheet placed upon-the faceof-the board and united therewithbythe adhesive material.

By the use of my com ounding machine the composite article is ormed andcut at one operation, 'the'adhesive material being incorporated with thestructure of the board,

30 and .the label sheet being immediately applied thereto, so that itwill -bemade to adhere strongly and be dried flat upon said board'.

In the accompanyin drawings: Figure 1 represents a longitu inalsectional view through the machine. Fig. 2 is-ja detail view relating tothe compounding roller. Fig. 3-. is a sectional plan view of the saidroller. Fig. 4 isa transverse sectional View of. the compounding roller.Fig.- 5 is a detail' relating to the compounding roller. Fig. 5? is adetail viewo'fthe cutters. Fig.

. 6 is a detail-sectional vielw of a heated pressure roller forpressing'the labeland fiber sheets together. ig. 7 is asectional planview of the upper series of pressurerollers and certain drivingconnections. Fig. -8 is a detail view of the adhesive rollers; Figs. 9and 10 are detail views.

The machine comprises a feed table 1 upon which the fiber boards areplaced.'

The label sheets which'are to be intimately associated with the fiberboards to make the composite article are preferably first placed upon aninclined feed board2. This table is hollow and is heated by steamintroduced through a pipe 3 and escaping through a suitable outlet 4..()n this table the label sheets are piled and heated and; they aretransferred from this storage table, one by one, to an inclined. feedtable 5 which also may be heated, like the table 2 just menlioned,- bysteam let in throughapipe 6 and roller the fiber boar escaping "througha suitable outlet. On

these two tables the label sheets are heated and are thus rendered,under certain circumstances, better condition for the subsequentfiClZlOIl'Of becoming united with the fiber board. The fiber boardpasses from the feed table 1 beneath the label feed table 5 to acompounding roller 7 where it receives upon its upper surface the edgeof'the label sheet to be united thereto, both sheets then passingbetween the compounding roller 7 and its pressure roller 8, by which thelabel sheet will be applied accurately-throughout its whole extent tothe fiber board as will,

be hereinafter. referred to. V

Previous to arrivin at the compounding" first passes through feedrollers 9, 10, and thence between 'the adhesive applying rollers 11, 12.'The upper one of these rollers is driven by a belt wheel 13 thereon andit rotates at the bottom of a, fountain 15 so as to take the adhesivetherefrom and grind the same into the fibrous structure of the board, soas to intimately incorporate the said adhesive with the fiber and form,as it were, a part of the board itself. In order to aid in this thoroughincorporation of the adhesive substance with the fibrous structure ofthe board, the adhesive is ground before being applied to the board andfor this urpose I use a roller 14 having slightly diff drential speed tothat of the roller 12, bearing upon the said fountain roller 12 andforming therewith the bottom of the fountain. This grinding roller isset slightly at an angle'to the main roller, as shown in Fig. 8, as Ifind that the tendency of this roller, being smaller than the mainroller, is to spring at its central portion away from the surface of themain roller and with a parallel arrangement of rollersthis allows theadhesive to pass through at this point in a greater quantity than at theends of the roller and also without being thor-v deflected by thepressure, because of its size,

and when the middle portion of the smaller and weaker roller springsaway the space between the rollers at this point will be the same asthat between the rollers at their ends where the intermediate spaceresults fr the angular arrangement of the roll 14 in respect to the roll12, and thus a uniform film is delivered. When an adhesive is used.which is influenced or is soluble by heat the applying rollers 11 and12 are heated similarly tothe pressure rollers to keep the adhesive influid condition.

When the fusible adhesive is already applied to the underside of thelabel sheet the fountain may be disused and the heat of the adhesiverolls 11 and 12 may be utilized to heat the fiber board and render itsuitable for receiving the label sheet with its adhesive coating. Roll14 is driven from roll 12.

The lower roll 11 is driven through gearing 16 from the shaft of theupper roll, and the lower feed roll 10 is driven through an idler; 17and ear 18 from lower roll 11.

'After passing between the rolls 11 and 12 and receiving the adhesivesubstance, the fiber board rests upon the endless traveling apron orseries of tapes 19 passing around rolls 20 and drivenin any suitablemanner. This endless apron carries the board towards the rear of themachine until its leading edge strikes a series of register and stoppins 21 projecting up from the compounding roll 7 and disposed atdifferent points along the same. These stop pins lie normally not onlyacross the path of the fiber board but also across the plane-of theinclined feed table 5 for the label sheets, so that the operator inorder to register the label sheet in relation to the fiber board andalso in relation to .the cutting devices hereinafter referred to, simplyfeeds the label sheet against the register pins so that its leading edgewill lie directly overthe leading edge of the fiber board. In order tosupport the said edge of the label in register with the leading edge ofthe board and ready to be pressed thereon, I employ a supporting plate24 forming an extension of the feed table 5. It has fingers 21" bearingupon the register pins and it is secured to the under side of the feedplate by screws 22 passing through slots 23 in theextension plate andinto the feed plate. This extension plate is retracted at the propermoment to allow the leading edge of the label sheet to-contact with thefiber board, and this retracting movement is etfected'by a lever 23, oneat each side of, the machine, fixed to a rock shaft 24 suitablyjournaled in the frame and operated by an arm 25 from a suitable-cam onthe shaft 26 journaled in the frame. The purpose of this extension plateis to furnish a temporary support for the leading edge of the labelsheet while the same is bein properly registered in relation to theleading edge of the fiber board and the cutting devices, and when theboard and label sheet have been properly registered against the pins 21the tem orary support 24 is retracted'and the labe sheet at its leadingedge is free to contact with the the label sheet upon the fiber board.This action takes place while the compounding roll 7 is stationary,'andas soon as the two sheets at their leading edges are pressed together bythe pressure roll 8 the compounding roll 7 begins to rotate and carriesthe fiber board and the label sheet to the rear, the pressure roll 8pressing the label sheet as it comes off the inclined table 5 down uponthe fiber board. The compounding roll 7 makes a number of revolutionsduring the passage over it of the fiber board and during this time theregister pins 21 remain retracted within the compounding roll as will behereinafter described. In rear of the c mpounding roll, a series ofpairs of heated p essure rolls 25 are arranged, between which thecomposite board passes after leaving the compounding roll, and by thesepressure rolls the label sheet is pressed firmly upon and mostintimately associated with the fiber board so that the article as itleaves the machine is of a substantially homogeneous structure, fiat anddry, the adhesive material being incorporated with the fibrous structureand the label sheet being closely united to the fibrous structure by theadhesive material.

After leaving the pressure rolls the composite board passes between apair of cutter rolls 26 which cut the board into a number of stripsexactly as registered by the registering pins and side guide a:, so thatthe printed design may be cut square and true in the same manner that anadditional color would be registered thereon, the board being soregistered that the cutters will operate be tween the designs on thelabel sheet, so that after leaving the machine the strips will beaccurately cut as printed to the proper size for making the can tubes orlike articles which carry labels on their outer sides. The cutter rollsare made up of circular cutting blades mounted upon a roller and are ofordinary form. In rear of the cutter rolls 26 I arrange a pair ofdelivery rolls 27. The pressure rolls are driven from the belt wheel 28on the shaft of one of them and the members of each pair'of pressurerolls are connected by gears 29, while idler pinions 30 communicate themotion between the gears of the lower set of pressure rolls. The cuttersare connected by gears 31 and are driven from one of the pressure rollsthrough an idler 32. The delivery rolls are also geared together, as at33, and are driven through an idler pinion 34. All the rolls aresuitably journaled in the frame of the machine as well as the idlerpinions.

action which takes place in connection with this roll is the retractionof its register pins '21, for which purpose the said pins are carried byblocks 35, Figs. 2-4, arranged to move substantially radially of therolland guided in ways 36, Fig. 3, of a stationary filling piece 37within the said roll. The blocks have lateral-1y projecting pins 37" entering inclined slots 38 in the slide 39', ar-

rangedto move longitudinallyjof the roll.

This slide, asshown in Fig. 4,'-is of substantially semi-circular formin cross section and is' fitted against the. filling piece 37. It'isnormally pressed in one direction to hold the blockswith pins 21'projectedfrom the roll, by means of a spring 40 bearing at one endagainst a block 41 fixed in one end of the roll and at its other endupon a shoulder 42 formed on the slide 39. The slidehas a phi 43, Fig.3, at its end projecting beyond the end of the roll and in the path of acam carried by a gear 45,'loose.on the journal 46 of the compound roll.Thisgear is rotated at proper intervals and its first actionwhenstart-ing from its, position of rest is to bring the cam 44 againstthe pin 43 of the slide and move the latter so that its incline slotsworking upon the pins 37 will retract the registering pins 21 within thecompounding roll. As soon' as this is effected and the leading edge ofthe label sheet has been-- pressed upon the fiber board by the descentof the pressure roll 8 as will be hereinafter a groove across which theclutch pin 48 extends; This groove 50 is intended toredescribed, thecompounding roll is set in rotation. For this purpose a clutchconnection is provided between the gear 45 and the compounding roll,consisting-of a projection 47 on the gear and a clutch pini48, adaptedto engage the same-and carried by a collar 49 fixed to thecompoundingroll and having ceive a crescent 51 on the end of a lever 52I loosely pivoted upon the main. driving shaft 53, as shown in Fig. 2.

The crescent controls the clutch1pini48 and when itis removed fromgroove 50 the clutch pin 48., will be forced by its spring 49,- Fig.{:3, intothe path ofthe projection 47 on the =55 gear 45 which isnow inrotation-and consequently the compounding roll will be rotatedint-unison with the said gear. This rotation takes place, as beforestated, after the registering pins have been retracted and, in order tocontrol this timing of the parts, the cresmotions arederived and thuseasily kept in unison, the said cam acting upon a roller poundmg rollhas ceased to rotate.

cam shown at 69 is representative suitable cams on the shaft 26.

cent carrying arm 52 is controlled by a cam on the shaft 26 from whichall. automatic carried upon an arm 55 connected with the crescent arm52. V I

After the fiber board and "label sheet have passed over the compoundingroll, the rotation of the said roll is stopped and the register pins 21are projected to stop and register the next fiber board and label sheet.For this purpose the crescent carrying arm 52 is moved by its cam tothrow the crescent into the groove 50. The crescent has an incline 54,Fig.2, up which the head of the clutch pin 48 will now ride, thusretracting said pin from engagement with the clutch projection on therotating gear 45, and as soon as-this disengagement takes place a pin 56on the clutch collar will contact with the pin 57 on the crescentcarrying arm and thus theroll 7 willbe arrested when its register pins21 come exactly where wanted. After the compounding roll" is at rest thegear wheel 45 continues to rotate long enough to carry the cam 44 awayfrom the pins 43, andfthis allows the spring 40 to exert itself to movethe slide 39 longitudinally and project the registering pin by means ofthe incline slot and pin connection 38-37 before described. As soon asthis has been accomplished the rotation of the gear wheel '45 is stoppedfor a predetermined length of time sufiicient to allQW the operator toproperly feed and register the label sheet and fiber board, For thisgear 58 loose on the main drive shaft 5.3 and purpose the clutch gear 45is driven from a carrying a clutch collar 59 similar to that describedabove, the clutch pin 60 of which coiiperates with the clutch projection61 on a clutch block '62 fixed to the main drive shaft ,53. This clutchis controlled by a crescent similar to that described above carriedon anarm 63 suitably pivoted on a bracket 64 on the main frame and'havin anextension 65 carrying a roller-engaged y a cam on the cam shaft 26. Thegear wheel 58 is arrested accurately in the desired position by means ofstop pinsj66 similar to those described. By means of this arrangementthe gear 45 w1llbe given an intermittent movement, the

intervals between its actions being properly determined for the feedinin and registering of the label sheet an will'be seen that the said gearwheel 45 is started in rotation earlier, and remains in fiber board. It

rotation longer,'than the compounding roll,

its excess of movement being utilized to move' the register pins in andout after the com- The crescent levers are pressed in opposition totheir cams. by means of springs 67, 68. The of any The pressure roller 8is lifted positivel by a rod69 connected to an arm 70, whic is in turnconnected to and operated by the crescent arm 63, the said rod 69' atits upper end is slotted as at71 and receives a pin on I fall by gravityas the register pins are retracted, so that the said pressure roll willfollow the downward movement of the pins and will accurately press theleading edge of the label sheet onto the fiber board, this action takingplace at just the moment that the register pins free themselves from thelabel sheet and fiber board. This lifting pressure roll 8 may be driventhrough suitable earing, but I prefer to let it remain idle, and I alsoprefer to control its weight by any suitable means of counter-balancing.As shown in the drawings the normal position of the register pins whenprojected and at rest is slightly to the right of the vertical axialplane of the compounding roll, the purpose of which is to insure asubstantial contact of the pressure roller 8 with the label sheet. Inother words, the leading edge of the label sheet is thus made to extendslightly'across the vertical axial plane of the compounding roll, sothat the pressure roller will make a good contact therewith when it islowered to a position directly over the axis of-the said compoundingroll.

In order to control the feeding in of the fiber boards, I provide a stop73 immediately in rear of the feeding-in rolls 9 and 10, carried by'ablock 74 arranged to move vertically in a suitable guide way in theframe and pressed normally upwardly by a spring 75. The block isconnected with a lever 76 pivoted at 77 and having a roller at its rearend acted on by a cam shaft 26.

-. The arrangement is such that, when the register pins 21 are projectedand are in the position shown in Fig. 1, the forward stop 73 is down andthe fiber board can be fed into the machine, but when the registeringpins are retracted and the compounding roll is in action the forward sto7 3 will be elevated to prevent the feeding in of a fiber board untilthe compounding roll has ceased to rotate and its registering pins havebeen projectedto arrest and register the label and oard, at which timethe forward stop is lowered and the next board can then be fed in, orthe exact relation between these stops and the registering pins-may beeasily adjusted'by turning the cam on its shaft so that the board ismade to come in at the right time to receive the new label sheet.

' The drive shaft 53 is. operated through a gear 78, Fig. 7, meshingwith one of the gears 29 on the forward lower pressure roll. This gear78 is loose on the shaft 53 but may be connected with the same to driveit by means of a clutch 79, Fig. 7, controlled by a lever 80 extendingto any convenient point for operation by the attendant.

The cam shaft 26 is driven from the shaft 53 by means of a pinion 80 onthe said shaft 53 and agear 81 on the cam shaft. All of the rolls aswell as the apron or tapes 19 are driven at the same surface speed.

The pressure rolls 25 are'heated to better unite the label sheet withthe fiber board and dry the same and also to assist the union when afusible adhesive is used, and for these purposes they are formed hollowand into the ends of one of them, as shown in Fig. 7, a steam pipe 82enters through a stufling box 84 arranged in the hollow journal of thesaid roll. From this roll the steam passes out through a pipe 85, theend of which is bent down as shown in Fig. 6, and is located at the farend of the roll from the steam inlet pipe 82. The pipe 85 passes outthrough the pipe 82 and connectswith an inlet pipe 82' of the nextadjacent roll, which inlet pipe extends through a stufling box in thejournal of the roll in a manner similar to that described above andthrough the whole system of rolls it proceeds similarly and is finallydischarged through a suitable outlet.

In a similar manner the steam may be applied to the adhesive set ofrolls to heat them when required or any convenient method of applyingheat to all the rolls and tables at will and as the circumstances of thework requires may be used.

In Fig. 5 I show the preferred form of register pins consisting or ascrew 86 threaded into a dove-tailed block 87 fitting in a recess 88 inthe upper end of the block 35. The screw is surrounded by a clampingsleeve 89, the foot of which rests upon the upper end of the block.

It will be understood that I use the terms label sheet for convenienceof description, as

it will be understood that the sheets'to be united with the fiber boardmay notalways carry a label.
